I have a plastic fold up chair I bough a menards that I used in my van when staying in it. It is hard to find a fold up chair you can use in a van. Most are too big. Sixteen dollars at menards. I weigh just under 200 and it works good. Plenty stout.
That swivel chair looks nice, say for outside lounging - but greatly doubt it would take my weight. Hate to have the swivel snap just under me! I am considering the basic old fashioned steel folding chair. Add a good cushion for comfort.
